Fluid Shifts in Heart Failure Might Cause Sleep Apnea Nocturnal Rostral Fluid Shift: A Unifying Concept for the Pathogenesis of Obstructive and Central Sleep Apnea in Men
ثبت نشده
چکیده
Methods: 57 men with stable HF, NYHA class I to III, and ejection fraction (EF) ≤45 were studied. Leg fluid volume (LFV) was measured by bioelectric impedance; right calf and neck circumference were measured (with lines drawn to ensure consistency) before and after sleep. Patients with predominant OSA (≥ 50% obstructive events) and apnea-hypopnea index (AHI) ≥15 were offered continuous positive airway pressure (CPAP).

Heart Failure Nocturnal Rostral Fluid Shift A Unifying Concept for the Pathogenesis of Obstructive and Central Sleep Apnea in Men With Heart Failure
Background—Obstructive sleep apnea (OSA) and central sleep apnea are common in patients with heart failure. We hypothesized that in such patients, severity of OSA is related to overnight rostral leg fluid displacement and increase in neck circumference, severity of central sleep apnea is related to overnight rostral fluid displacement and to sleep PCO2, and continuous positive airway pressure a...

متن کاملDiffering relationship of nocturnal fluid shifts to sleep apnea in men and women with heart failure.
BACKGROUND In men with heart failure, nocturnal rostral fluid shift is associated with an overnight increase in the neck circumference (NC) and with severity of obstructive sleep apnea. Because the prevalence of obstructive sleep apnea is lower in women than in men with heart failure, we hypothesized that less fluid would shift into the neck in association with less severe obstructive sleep apn...
متن کاملRostral overnight fluid shift in end-stage renal disease: relationship with obstructive sleep apnea.
BACKGROUND In both healthy male subjects and men with heart failure, the severity of obstructive sleep apnea (OSA) is related to the amount of fluid displaced from their legs into the neck overnight. Whether overnight rostral fluid shift contributes to the pathogenesis of OSA in patients with end-stage renal disease (ESRD) is unknown. We hypothesized that the change in neck circumference (NC) a...
متن کاملImpact of nephrotic edema of the lower limbs on obstructive sleep apnea: gathering a unifying concept for the pathogenetic role of nocturnal rostral fluid shift.
BACKGROUND Nocturnal rostral fluid shift has been suggested to be a risk factor for obstructive sleep apnea (OSA) in healthy subjects after lower body positive pressurization. It remains unclear whether this may apply to subjects with nephrotic lower limb edema and, if so, whether disease remission may reverse the accompanying OSA. METHODS Patients who presented with steroid-responsive primar...
